It's Up to You

Description

Get other people to comply with your requests by pointing out that they have
full freedom in deciding what they are going to do.

Point out that they are welcome to choose any option, especially when any of
these choices is good for you. You can also point them at one 'best' choice and
then say 'It's up to you' though with an implication that choosing other than
the way you have indicated would be unwise.

Example

Do you want the blue one or the yellow one? It's up to you.

I'd really like to go out for dinner, but it's up to you.

You don't have to go if you don't want to, but if you stay
everyone will be really disappointed.

Discussion

Unless you have direct power over the other person, then this is effectively
an obvious statement. Of course they can decide as they wish. Even if you could
coerce them, we are all autonomous agents and still have the option of refusing.

The real principle at work here, then, is not really empowering them, but
emphasising their freedom, confirming they are in
control. When they do feel
in control they are more likely to accept suggestions. When people feel that
others are in control they may react in a contrarian way,
resisting persuasion just as a way
of showing they can still control their fate.

This is often used when you are offering a number of options and want to
imply that they can choose any of them. This is still
assumptive as it does not
explicitly include choosing none of them.

'It's up to you' can also include a veiled threat, implying that, while they
of course do have this choice, you have a clear preference and if they choose
otherwise you will be very unhappy with them. This is typically used in
relationship situations.

Saying 'It's up to you' also emphasizes the responsibility that the person
has, and that if their choice does not turn out well, they cannot blame you for
making them choose in a particular way. This can avoid later blame and get them
to think more carefully about their options. This is particularly useful when
you want them to take less risks in their decisions than they might otherwise
choose.
